Military/Civvy Trailer Power Sockets

Please can anyone help me answer this question?

I have a civvy 1995 300 TDI defender 110 with NATO tow hitch for my Sankey trailer. It has two standard civvy power sockets at the rear (12N and 12S) —trailer lights and 12V power from the spare battery. These sockets are always getting damaged because they are not flush with the rear cross-member and are fitted below the tow hitch (as per most civvy land rovers).

Do you know if it is possible to fit military trailer light sockets, with the sprung flat cover/flap, to my cross-member, ideally one either side of the tow hook? I would post a photo here if I knew how to do it ( can anyone help with that?)!

Assuming these military mounts and flaps are large enough for the inner part of 12N and 12S sockets, there are no suitable holes to use in my cross-member and I wonder if cutting the requisite holes would weaken the cross-member (do the army use reinforced cross-members or what?)

Many thanks in anticipation of your help and expert knowledge!

The military electrics go in the hole on the rear crossmember to the RHS of the NATO hitch. I left mine where it was when I put the Dixon drop bar on just add a standard power socket to the drop bar mounts.

I then use a NATO hitch on a drop plate so I can change the hitch to suit between our sankey and the normal trailers. The military electrics are different to the civvie ones as they use a lot more wires as I found when we restored ours.
